Severity: normal
This little program makes gtk/glib segfault:
## start ##
#include <gtk/gtk.h>
int main(int argc, char** argv)
{
char** myargv = (char**)malloc(sizeof(char*)*3);
int myargc = 2;
myargv[0] = "test";
myargv[1] = "-calendar";
myargv[2] = 0;
gtk_init(&myargc, &myargv);
return 0;
}
## end ##
Backtrace:
Program received signal SIGSEGV, Segmentation fault.
0xb7b60266 in g_option_context_add_main_entries () from /usr/lib/libglib-2.0.so.0

#5 0x0804875d in main (argc=1, argv=0xbffff824) at checkargs.c:12
If I change "-calendar" into "--calendar", no segmentation violation takes place.
This bug occurs when running mozilla-sunbird (both prebuilt versions from mozilla.org
and cvs builds).

Hi,
Are you speaking about this bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=3D74303 (comment #24) ?
This is a firefox issue, gtk_init remove the parsed options and update
argc but firefox doesn't use the updated value.
You program is not correct, you should not change the argc/argv values,
argc is the number of elements in argv. I'm closing this bug since
that's not a glib one.
Cheers,
Sebastien Bacher
